Lennox 27A28 Heater
The Lennox 27A28 (Model ECB29-12.5CB-8P) is a high-performance 12.5 kW electric heat kit engineered for seamless integration into Lennox air handler and blower cabinet systems. Operating on a 208/230V power supply, this resistive heat assembly serves as the primary auxiliary or emergency heat source when ambient temperatures drop below the heat pump’s balance point. For contractors performing service or retrofits, this electric heat strip is designed specifically for the ECB29 series, ensuring the heating elements align perfectly within the factory cabinet to maintain optimal airflow and static pressure. The Lennox 27A28 heater utilizes a multi-stage configuration to manage electrical loads efficiently, providing a reliable temperature rise without stressing existing control architecture. Whether you are addressing a failed sequencer or upgrading a system for higher heating demand, this direct-fit HVAC auxiliary heat strip ensures consistent performance and safety in residential or light commercial installations.
Key Benefits- 12.5 kW Heat Output: Delivers robust resistive heat for auxiliary or emergency operation.
- OEM Compatibility: Precision-engineered for Lennox ECB29-12.5CB-8P air handler integration.
- Voltage Versatility: Fully rated for 208/230V single-phase electrical systems.
- Direct-Fit Installation: Maintains factory cabinet geometry for streamlined field replacement.
- Staged Heating: Supports efficient load handling and precise temperature control.
What systems are compatible with the Lennox 27A28?
This heat kit is purpose-built for Lennox ECB29 series air handlers and compatible blower cabinets designed for 12.5 kW resistive heat loads.
Can this be used as the primary heat source?
While it provides significant output, it is typically utilized as supplemental heat for heat pump systems or as an emergency heat source during compressor failure.
What are the electrical requirements for the ECB29-12.5CB-8P?
It requires a 208/230V power supply and must be fused according to the air handler's nameplate data to handle the 12.5 kW resistive load.
